Do it exactly as you wrote it. For the negative exponent use the change sign key [ -]. The question is whether you are aware of the meaning of the EE key.
The EE key is a shortcut for x10^. Thus 1EE3=10^3=1000.
As to the other number (the electron mass) its value is 9.1x10^(-31) kg which you enter as you typed it 9.1 [EE] [( -)]31 [=]

I dont understand why I keep getting the wrong exponet in trying to figure out 1500nm divided by 10^9. the answer I get is 1.5 *10^-7 -but the answer is 1.5*10^-6. What am I doing wrong?

Without knowing exactly what you're doing I can't be sure, but I suspect you're entering the 10^9 as something like 1 0 EE 9 .

1 0 EE 9 gives you 10 * 10^9, which is 10^10. You should be doing this as 1 5 0 0 / 1 EE 9 = .

Make sure you use the +/- key just to the right of the decimal point key when entering negative values, including exponents.

I have to use eng mode. When I type (54.2*10ee-3)*(37*10ee9) I get 2.0054ee11. My teacher says that I should have 2.0054ee3. Does my calculator is broken?

No! Your calculator is not broken. However you are not using the EE button correctly, or you are not aware of its meaning.
The EE key is a shortcut for 10 to a power and the 10 is already included.

Here is an example.To enter the [EE] you use [SHIF][,] where the comma [,] is the key between [SIN] and [7] in the column under [MODE]. To enter a negative exponent you use the change sign key (-), the one at the bottom of keypad below 3 and to the right of the decimal mark [.]
To enter 54.2 x10^(-3) you type in 54.2[,] [(-)]3
To enter 37x10^(9) you type in 37[SHIFT] [,]]9

The correct result is 2.0054x10^9 and your calculator will show you 2.0054E9

However by typing in 54.2*10[EE]-3 your are in fact entering 54.2x10x10^(-3) and by typing 37*10[EE]9 you are entering 37*10*10^9 and your final result is in fact multiplied by 100, hence the value you are getting 2.0054E11

Try to multiply (20x10-9) (1x10-9)

If you use the exponent rules you do not need to use a
calculator for this particular case. Anyway to enter power of 10 exponents you use the [EE] key. See screen capture below.

20 [EE] (+ -)9 [X] 1[EE] (+ -) 9

HELP, I can't seem to figure out scientific notations with my Texas Instrument TI-30XA. I've searched for hours on the web. Here's the problem: 7.82 x 10^10 / 63.55 = 1.23 x 10^9. But when I input 7.82 x...

The error comes from the lack of understanding of the meaning of the notation used by the calculator manufacturers.
The [EE] is a "shorthand" notation for times 10 to the power of .
To convince you of it try entering

1[EE]0 [=] this is 1*10^0=1*1=1
1[EE]1 [=] this is 1*10^1=1*10=10
1[EE]2 [=] this is 1*10^2=1*100=100

When you enter 7.82x10[EE]10
you are calculating

Hope it helps.

I need to put in the number 10 to the negative nine.

If you have the [EE] key (sometimes labeled [Exp], or [times 10 to the x], you enter your expression as 1[EE](-9). If you do not have that key you can use the general power key [X to the y] or [Y to the x] or [^] depending on calculator 10[^](-9) = 0.000000001 or equivalently 1.0000x10^(-9)

EE or EXP are shortcuts for times 10 to the power.
Hope it helps.

How do I calculate exponential functions?

The y^x button is right next to the x^2 button. It is labled with an x raised to a square box (which I will write as x^box). Thus, if you enter (for example)
